A Swiss SIM card for tourists gives you local mobile data, a Swiss number, and predictable prepaid costs without relying on your home carrier’s roaming. The main local networks are Swisscom, Sunrise, and Salt, and visitors can buy prepaid service after identity verification. Your best setup depends on trip length, data use, whether you need local calls, and whether you will cross into neighboring countries.
Quick Answer
Tourists can buy a Swiss prepaid SIM or eSIM from Swisscom, Sunrise, or Salt after identity verification. Compare the total cost, data allowance or speed, local calls, and roaming coverage. Swisscom sells fixed-duration tourist flats, Sunrise charges by 24-hour use, and Salt combines prepaid credit with daily or data-pack options.

Key Takeaways
- Bring a valid passport or other accepted identity document. Swiss providers must identify customers who buy a SIM.
- Swisscom, Sunrise, and Salt use different prepaid models, so compare the starter cost with the charge for data or daily use.
- Switzerland is outside the EU/EEA “Roam Like at Home” area, so do not assume an EU mobile plan includes Swiss roaming.
- 4G population coverage is almost complete, but mountain valleys, tunnels, and remote routes can still have weaker reception.
- An eSIM can save time if your phone supports it; a physical SIM remains useful for phones without eSIM support.
How to Purchase a Swiss SIM Card
You can buy prepaid mobile service online or after you arrive in Switzerland. The easiest physical-SIM locations are operator shops, airports, and major railway stations; Switzerland Tourism also lists kiosks, post offices, and grocery stores as common prepaid SIM outlets.
Keep a valid passport or another identity document accepted by the provider ready. Identity registration is not optional: Salt explains that Swiss law requires SIM customers to be identified, while Sunrise applies an online ID and video-selfie check for prepaid eSIM registration.
- Choose your operator and prepaid model. Decide whether you want a fixed-duration tourist plan, pay-per-use prepaid service, or a data pack.
- Choose eSIM or a physical SIM. eSIM avoids handling a plastic card, but your phone must support eSIM and be unlocked.
- Complete the identity check. Present your ID in a shop or follow the provider’s online verification process.
- Pay or add enough prepaid credit. Some offers include starting credit, while others charge a package price directly.
- Install and test the line. Confirm that mobile data works before leaving the shop or your reliable Wi-Fi connection.
eSIM or Physical SIM?
An eSIM is usually more convenient if your phone supports it because you can keep your physical home SIM in the device. Swisscom sells its tourist prepaid service as either eSIM or physical SIM, while Sunrise lets foreign visitors register a prepaid eSIM with a foreign address.
A physical SIM is the safer choice for older phones or devices without eSIM support. If you buy in person, operator staff can also help confirm that your phone is unlocked and compatible.
Benefits of Using a Swiss SIM Card
A local Swiss SIM gives you mobile data for maps, public transport information, accommodation messages, restaurant searches, and other travel tasks without depending on hotel or café Wi-Fi. It can also provide a Swiss phone number for local calls and texts.
Public Wi-Fi is useful, but it does not cover an entire trip. For example, SBB provides free Wi-Fi at 80 Swiss stations, yet you may still need mobile data between stations, on local transport, or in rural areas.
A local prepaid line also gives you clearer cost control than open-ended roaming. You decide how much credit or which package to buy, and you can top up only when needed.
Cost Savings with a Swiss SIM Card
A Swiss prepaid SIM can reduce mobile costs when your home plan charges high roaming rates in Switzerland. The real comparison is your home carrier’s Swiss roaming price versus the full local cost, including any starter fee, included credit, daily charge, and data pack.
| Current prepaid examples, checked October 1, 2026 | |
|---|---|
| Swisscom Prepaid Flat 7 | CHF 20 for 7 days |
| Sunrise Unlimited CH basic rate | CHF 2.50 per 24 hours used |
| Salt Unlimited Surf | CHF 1.99 per day |
| Salt 5 GB data pack | CHF 14.95 for 30 days |
Swisscom’s tourist Prepaid Flat currently costs CHF 20 for 7 days, CHF 40 for 15 days, CHF 65 for 30 days, or CHF 150 for 90 days. Each includes unlimited data in Switzerland at up to 50 Mbit/s, unlimited calls within Switzerland, and unlimited SMS in Switzerland and abroad.
Sunrise Prepaid Unlimited CH charges CHF 2.50 for each 24-hour period in which you use mobile data, calls, or SMS in Switzerland. The CHF 19.90 starter pack includes CHF 20 of credit, enough for about eight charged 24-hour periods at the current domestic rate.
Salt PrePay currently advertises a free SIM with CHF 10 starting credit. Its standard prepaid offer lists unlimited Swiss data for CHF 1.99 per day, plus 30-day packs of 1 GB for CHF 9.95, 5 GB for CHF 14.95, and 25 GB for CHF 29.95.
Some providers may also run tourist promotions with local perks such as attraction or transport discounts. Because promotions change, treat those extras as a bonus rather than the main reason to choose a plan.
Using a Swiss SIM Card for Data Roaming
A Swiss SIM card does not automatically give you low-cost data in France, Germany, Italy, Austria, or other nearby countries. Switzerland is outside the EU/EEA roaming zone, and the EU’s Roam Like at Home rules do not cover Switzerland.
If your trip crosses borders, choose a package that explicitly includes the countries you will visit. Sunrise’s current Unlimited Europe 7 and Europe 30 prepaid options include mobile data in Switzerland and 46 European countries, with 60 GB of high-speed data in the included European countries before speed may be reduced to 256 kbit/s. Data used in Switzerland does not count against that 60 GB allowance.
Salt also sells separate Europe roaming data packs. Its current PrePay page lists a one-week package with unlimited data including 5 GB at high speed for CHF 14.95, and a one-month package with unlimited data including 20 GB at high speed for CHF 29.95. Roaming terms can differ from domestic terms, so base your choice on the actual countries in your itinerary.
Tips for Choosing the Right Swiss SIM Card Plan
The right Swiss SIM card plan is the one that matches your trip length and actual phone use. Compare total cost, high-speed data, domestic calls, roaming countries, and whether you want to activate before arrival.
Data Needs and Daily Use
If you will use maps, upload photos, stream video, or tether a laptop, prioritize a larger or unlimited data allowance. For lighter use such as messaging, tickets, email, and occasional maps, a smaller data pack can be enough.
Pay attention to speed limits as well as the word “unlimited.” Swisscom’s tourist flats, for example, currently cap download speed at 50 Mbit/s, while some roaming options reduce speed after a stated high-speed allowance.
Duration of Stay
For a fixed one- or two-week trip, a fixed-duration tourist flat can be simple because the price and expiry date are clear. A daily-charging plan can be better if you will use mobile service only on selected days, while a 30-day data pack fits longer stays with predictable data needs.
Also check when validity starts. Swisscom says its tourist prepaid period begins when the eSIM connects to the Swisscom network and is used; Sunrise says its Europe package validity starts at first use and can be activated within 365 days after purchase.
Coverage and Itinerary
All three national networks cover most populated areas well, but your route matters more than a national percentage. If you will spend time in remote valleys, hiking areas, or small mountain villages, compare the provider’s coverage map for those exact places before buying.
Local Number, Calls, and eSIM Convenience
If you need a Swiss number for hotels, restaurants, tour operators, or local contacts, a local prepaid SIM is more useful than a data-only travel product. If your phone supports eSIM and dual-SIM use, you can often keep your home line installed while using the Swiss line for data and local calls.
Activating and Setting Up Your Swiss SIM Card
Activation is usually quick once the provider has verified your identity. Most modern phones load the network settings automatically, so manual APN changes should only be necessary if the provider specifically instructs you to make them.
- Confirm the phone is unlocked. A carrier-locked phone may reject another operator’s SIM or eSIM.
- Install the SIM or eSIM. Insert the physical SIM or follow the provider’s eSIM installation process while connected to reliable internet.
- Set the Swiss line for mobile data. If you use dual SIM, keep data roaming off on your home line unless your home plan includes Switzerland.
- Wait for network registration. The phone should connect to the Swiss mobile network automatically.
- Test mobile data and a call. Confirm both work before you depend on the line for navigation or transport information.
Pro Tip: Keep your SIM packaging, assigned Swiss number, login details, and top-up instructions until the end of the trip. They can save time if you need support or have to reinstall an eSIM.
If mobile data does not work, first confirm that the Swiss line is selected for cellular data and that the plan has active credit or an active package. Then restart the phone or use the provider’s official support instructions for network and APN settings.
Using a Swiss SIM Card for Local Calls and Texts
Local calls and texts depend on the plan, so they are not always free after the initial purchase. Swisscom’s tourist flats and Sunrise’s charged Unlimited CH periods include domestic calling, while Salt’s standard PrePay model charges separately for calls and SMS.
As checked on October 1, 2026, Swisscom tourist flats include unlimited calls within Switzerland and unlimited SMS in Switzerland and abroad. Sunrise Unlimited CH includes unlimited calls and SMS within Switzerland during each paid 24-hour usage period. Salt lists domestic calls at CHF 0.49 per call for up to 60 minutes and SMS at CHF 0.12 each.
A Swiss number can be helpful when you need to call accommodation, restaurants, transport providers, or other local services. It also lets other travelers or local contacts reach you without calling your home-country number.
Using a Swiss SIM Card for International Calls and Texts
International calling is usually separate from the domestic prepaid allowance. Rates vary by destination and provider, so a Swiss SIM should not be assumed to make every international call cheaper than your home service.
Swisscom’s tourist flat includes unlimited SMS abroad, but its included voice calls are within Switzerland. Sunrise and Salt both publish international calling rates by country or country group. If you mainly need to speak with family abroad, internet-based calling over your prepaid data can often avoid per-minute international voice charges.
Before making long international calls, make sure you know whether the destination is included in a package or billed separately. This avoids using prepaid credit faster than expected.
Understanding Swiss SIM Card Coverage
Switzerland has very broad 4G and 5G coverage, especially in populated areas. The Federal Communications Commission’s May 2026 coverage report says almost 100% of the population had LTE/4G coverage at the end of 2025.
The same report says Swisscom reached 99% of the population with 5G by the end of 2025, Sunrise covered more than 99% with 5G, and Salt reported 99.9% population coverage when all its network technologies were combined. Population coverage does not mean every hiking trail, tunnel, mountain pass, or isolated valley has a strong signal.
Older-phone compatibility also matters. Sunrise switched off 3G in mid-2025, Swisscom ended 3G at the end of 2025, and Salt was expected to keep 3G until the end of 2026. An unlocked phone with modern 4G/LTE support is therefore a much safer choice than relying on an older 3G-only device.
What to Do with Your Swiss SIM Card After Your Trip
You can keep a prepaid SIM for a future visit, but inactivity rules can cause the number and remaining credit to expire. Swisscom says its prepaid SIM becomes invalid after 12 months without use; Sunrise says its prepaid number is deleted after 17 months without qualifying use.
If you do not plan to keep the number, remove the physical SIM or delete the eSIM profile from the phone after you are finished with it. Before letting a number expire, change any account that uses that Swiss number for login or verification so you do not lose access later.
Some providers or retailers may also accept old SIM cards for recycling. If that option is not available, destroy the chip before disposal so the card cannot be reused.
